Iran Accelerates Nuclear Site Repairs And Fortifications Despite Trump's Stern Threats

New satellite imagery shows that the Islamic Republic of Iran has been actively repairing and fortifying several military and nuclear-linked facilities, a development experts say reflects Tehran’s efforts to protect critical infrastructure amid escalating tensions with the United States and Israel. The images, analysed by independent analysts and global news agencies, offer a detailed look at reconstruction and concealment work taking place at several strategic sites across the country.

The most striking changes are visible at the Parchin military complex, located about 30 km (20 miles) southeast of Tehran. Satellite photos comparison from late 2024 through early 2026 show a large structure at the site gradually being encased under concrete and then covered with soil, effectively masking it from aerial observation. This follows a reported Israeli airstrike on the facility in October 2024. Western intelligence has long regarded Parchin as a sensitive site in Iran’s defence and weapons development infrastructure, including past weapons-related tests.

At the Isfahan nuclear complex, imagery indicates that tunnel entrances damaged by US strikes during a 12-day conflict last year have been completely buried under soil. Analysts say this backfilling could dampen the effects of potential airstrikes and make ground access difficult for any future special forces operations. Similar fortification efforts are underway near the Natanz uranium enrichment site, where tunnel entrances at a nearby mountain facility have been hardened, with heavy equipment visible in satellite pictures.

The reconstruction efforts extend beyond nuclear facilities. Satellite analysis shows that missile bases near Shiraz and Qom, damaged during previous conflicts, are also being repaired or reinforced. At the Shiraz South Missile Base, images comparing mid-2025 and early 2026 show ongoing reconstruction and clearance work at key compounds. A damaged building at the Qom base has been fitted with a new roof after repairs beginning late last year.

The developments come as diplomatic efforts between Washington and Tehran over Iran’s nuclear programme remain tense. US officials have reiterated that all options, including military action, are on the table should talks fail, and have continued pressure on Iran through both political and military postures. Satellite imagery of these fortification efforts has been interpreted by some analysts as Iran’s attempt to harden vulnerable sites before any potential escalation.

Iran’s government has historically denied pursuing nuclear weapons and maintains its activities are for peaceful purposes. Nevertheless, the extent of reconstruction and concealment seen in recent imagery is likely to intensify international scrutiny and complicate diplomatic negotiations aimed at resolving ongoing tensions over Tehran’s nuclear ambitions.
